"It's impossible to keep a secret ... especially one as wonderful as this. We want to be the first to share this great news with everyone that we are expecting a new addition to our family. Love, John, Kelly and Ella"

Their daughter Ella Bleu is 10 -- and, of course, in January 2009 they lost their son Jett, who was 16 at the time.

While the announcement is wonderful news, it's rife with questions: Is it a biological child? Are they adopting? When is the child expected? Is it even a child? A "new addition" can mean a lot of things.

In any case, it's so nice to see the family expecting such excitement after experiencing so much heartbreak.

What do you think of John Travolta and Kelly Preston's announcement about an addition to their family?
